These are plug-and-play modules which draw power from the USB cable - no external power supply is required. All configurable options (including individual channel ranges) are software programmable, and the modules are fully software calibrated.Both modules feature eight analog voltage input channels that are processed through a single A/D converter. The analog inputs to the OM-USB-1208FS are software configurable for either eight 11-bit single-ended or four 12-bit differential inputs. The analog inputs to the OM-USB-1408FS are software configurable for either eight 13-bit single-ended or four 14-bit differential inputs.These modules have one 32-bit counter channel. The digital I/O channels are software programmable for input or output. Both models have two 12-bit analog outputs. The packaging for the OM-USB-1208FS and OM-USB-1408FS ensures ease of use in a variety of applications.OM-USB-1208FS shown actual size.The OM-USB-1208FS and OM-USB-1408FS data acquisition modules are supplied with TracerDAQsoftware which is a collection of four virtual instrument applications used to graphically display and store input data and generate output signals:• S trip Chart—Log and graph values acquire from analog inputs, digital inputs, temperature inputs and counter inputs• O scilloscope—Display values acquired fromanalog inputs• F unction Generator—Generate waveforms for analog outputs•R ate Generator—Generate waveforms for counter outputsT racerDAQ PRO is an enhanced version of TracerDAQ.

Driver support and detailed example programs are included for Universal Library programming libraries for Microsoft® Visual Studio® programming languages, and other languages, including DASYLab®, and ULx for NI LabVIEW®(comprehensive library of Vls and example programs compatible with 32-bit and 64-bit LabVIEW v8.5 through 2013) and InstaCal™ installation, calibration andtest utility - powerful solutions for programmers and nonprogrammers alike. These modules operate under Microsoft Windows® XP (32-bit only) and VIST A/7/8 (32-bit and 64-bit) operating systems.ANALOG INPUTOM-USB 1208FS: These devices provide eight, 11-bit single-ended analog inputs or four, 12-bit differential analog inputs.OM-USB 1408FS: These devices provide eight, 13-bit single-ended analog inputs or four, 14-bit differential analog inputs.All devices support software selectable ranges that provide inputs from ±1V to ±20V in a differential configuration, and ±10V in a single-ended configuration.OM-USB-1408FS8 SE/4 DIFF48 kS/s max2±6.0 mA per Pin1GENERAL INFORMATIONSAMPLING RATE: When scanning continuously to computer memory (hardware-paced mode), theOM-USB-1208FS can sample at a maximum of50 kS/s, and the OM-USB-1408FS can sample ata maximum of 48 kS/s.CHANNEL-GAIN QUEUEThe channel-gain queue feature lets you configure a list of channels and gains for each scan. Each channel can have a different gain setting. The gain settings are stored in a channel-gain queue list that is written to local memory on the device.The OM-USB-1208FS and OM-USB-1408FS channel-gain queue can contain up to 16 channels listed in any order.ANALOG OUTPUTThe maximum analog output update rate for all devices depends on several factors, including USB port speed. Both devices offer two 12-bit analog outputs with a range of 0V to 4.096V.When updating continuously from computer memory (hardware-paced mode), one analog output updates at a maximum rate of 10 kS/s; two analog outputs update simultaneously at a maximum rate of 5 kS/s each. DIGITAL I/OAll devices provide 16 TTL-level digital I/O lines. Digital I/O can be programmed on each 8-bit port (Port A and Port B) for either input (default) or output.EVENT COUNTER INPUTEach device supports one 32-bit TTL-level counter that accepts inputs up to 1 MHz.SPECIFICATIONSANALOG INPUTA/D Converter Type: Successive approximation Channels: 8 single-ended (SE) or 4 differential (DIFF), software programmableInput Common-Mode Voltage Range for Linear Operation:SE Mode: CHx to GND, ±10V maxDIFF Mode: CHx to GND, -10V min, 20V max Absolute Maximum Input Voltage: CHx to GND,±28V maxInput Impedance: 122 kΩRanges: Software selectable on a per-channel basis SE Mode: ±10VD IFF Mode: ±20V, ±10V, ±5V, ±4V, ±2.5V, ±2.0V,±1.25V, ±1.0VThroughput: Maximum throughput scanning to computer memory depends on the computer being used.
